Answer is : (a) 1
A normal human inherits only one sex chromosome (either X or Y chromosome) from father. Sex chromosomes, determine whether an individual is male or female. In human and other mammals these are designated by scientists as X and Y. In humans, the sex chromosomes comprise one pair of the total of 23 pairs of chromosomes. The other 22 pairs of chromosomes are called autosomes.
